Want to look slim and sharp in your dress shirt, and not like you're wearing a poofy blouse? This video from Birchbox Man demonstrates how to use the military tuck to do just that (whether you're a guy or a gal).

Basically, you pinch the excess fabric at the side seams and fold it back when you tuck it in. We've mentioned this anti-billowing trick previously, but the video gives us a closer look (scrub to the 0:53 mark to watch it).
